Abstract: PROBLEM TO BE SOLVED: To enable significant reduction in the operation time, by carrying out processing with a specified polyphosphate compound dispersant prior to adsorption of a water-soluble surface active agent, in preparing a magnetic fluid substituted for the water-soluble surface active agent. SOLUTION: After a polyphosphate compound dispersant expressed by the formula (where M indicates an alkaline metal and n indicates an integer not smaller than 2) and then a water-soluble surface active agent are added to ferrite group fine particles of a water-soluble suspension, a carbohydrate extraction solvent is added, thus carrying out extraction of ferrite group fine particles for adsorption of the water-soluble surface active agent. A flocculating solvent is added to the extracted solution, thus obtaining cake-like fine particles. After the fine particles are dispersed into a low boiling point carbohydrate solvent, the low boiling point carbohydrate solvent is removed and heating is carried out at about 150 to 350 deg.C, thus performing adsorption processing of N- polyalkylene polyamine substitution alkenyl succinate imide.  After that, a low boiling point carbohydrate solvent is added again, and after a low steam pressure base oil of 0.1 mmHg or less at 25 deg.C is added to carry out dispersion processing, the solvent is removed.

Abstract: PURPOSE:To prevent intrusion of a large amount of charged particles in plasma into a sample by the method, by which the outer product vector of magnetic field vector and the vector directed from the first plate electrode to the second plate electrode has the vector component that is directed from the center of the second plate electrode into the outward direction on the surface of the sample. CONSTITUTION:Magnetic fields 21 and 22 having the magnetic flux density of 100 gauss are formed around a sample 10 with electromagnetic coils 1, 2, 3 and 4. At this timer the magnetic field 21, which is formed with the first set of the electromagnetic coils 1 and 2, and magnetic field 22, which is formed with the second set of the electromagnetic coils 3 and 4, are offset on the sample 10. Therefore, the increase and deviation of the plasma density caused by the large magnetic field are eliminated. Especially, excessive unnecessary charged particles, which break a gate oxide film, are drifted and moved to the outside of the sample 10 by the magnetic fields 21 and 22. Thus, the intrusion of the plasam current caused by the large amount of the charged particles into the sample 10 is prevented, and the MOS-structure device indicating the excellent gate-oxide-film characteristics can be manufactured.
